Application February 8, 1945, Serial No. 576,786

This invention relates to new and useful irnprovements in inflatable raisable sh nets.

More particularly, the invention proposes an improved fish net which is characterized by a basket-like net body having the usual open top. It is proposed to provide an inflatable tube arranged so that it may be collapsed to permit the net to sink in Water, and may be inflated to cause the net to rise and so catch the fish.

The invention proposes to mount sinkers, in the nature of a chain, around the top portion of the net to sink the net when the inflatable tube is deflated.

It is proposed to connect a small diameter tube with the inflatable tube in such a way that Vthe inflatable tube may be filled with air when it is required that the fishnet should rise.

Still further the invention proposes the pro- `vision of a flexible cord-like member extending v fact that the air would be excluded from the interior of the tube.

Still further the invention proposes an inflatable raisable sh net as briefly mentioned, which is simple and e'icient and which may be manufactured and Sold at a reasonable cost.

.For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming. a material part of this disclosure:

Fig. 7 is a transverse sectional View taken on the line 'I--l of Fig. 6.

The inflatable raisable fish-net, in accordance with this invention, vincludes a basket-like net 3 Claims. (Cl. 43-7) body II) constructed of the usual cords, or similar materials, and having an open top. An inflatable raisable tube II is mounted around the open top; an inlet valve I2 is provided for inilating the tube II and a discharge valve I 2a is provided for deflating the same. The tube II is secured to the top edge portion of the net body I0 by a cord I4 wound around the tube and laced through the top portion of the net body I0. Sinkers I5 are mounted around the open top of the net body I0. These sinkers I5 comprise a length of chain secured in position about the open top of the net body Iby having the cord I4 laced through certain of the links thereof.

.A small diameter rubber tube I6 extends from the tube I I and carries the tire valve I2 through which air may be supplied for inflating the tube II. The bottom of the net body I0 is partially restricted with a constricting rubber ring I8 mounted about the bottom portion of the .net body II) a short distance above the extreme bottom end. The ring I8 is tied withv cords 20, or in any other way secured so as to hold the bottom portion of the net body II) in a gathered condition. A draw string 22 is threaded through a hem portion 23 formed along the open bottom of the net body Ill. This draw string 22 is normally tied so as to hold the bottom of the net body I0 closed. When the draw string 22 is slackened it is possible to discharge fish caught in the net body through the open bottom of the net body.

A exible cord-like member 25 formed with longitudinally vextending external air grooves 26, is located within the inflatable tube II for preventing complete collapsing of the inflatable tube II. This cord-like member 25 has a central slack area located directly opposite the point where the tube I6 is connected with the tube II. see Fig. 6. The cord-like member 25 is retained in a serpentine formation within the tube II by spaced rings 21 mounted in position in the tube II. The rings 2'I have loop portions 28 through which the cord-like member 25 passes. The oo llapsible tube II may be constructed of a length of rubber hose, into the ends of which the rings 21 are forced, so that they maintain fixed positions. The ends of the rubber hose are vulcanized, or in any other way connected together so as to seal the inflatable tube II.

lThe operation of the inflatable raisable iish net is as follows:

is discharged from the tube I I by compressing it.

3 The discharge valve lZa is closed and the net is then dropped into water and it will sink. The inflatable tube Il cannot be totally collapsed by the pressure of the water against the sides thereof because of the flexible cord-like member 25 and the rings 21.

When it is desired to raise the net, air is blown or pumped into the tube iB to by-pass the inlet valve l2 and inflate the tube Il. The air can always .reach around the inflatable tube .H because the cord-like member 25 pevents the tube Il from collapsing completely. The air can always run along through the grooves 26 in the cord-like member 25 and .in this way reach all points within the collapsible tube l l. When the tube Il becomes inilated it will iloatfand "will raise the sh net body IU. Then the top portion of the net body Il] may be squeezed closed, and the draw string 22 opened, so that the catch of sh may be funneled out of the net body I .through the .ring i8.

While I have illustrated 1anddescr-ibed theplepreferred embodiments of .my invention, :it :is .to be .understood that I Ydo not limit myself .to ythe precise constructions herein disclosed and tthe rig-ht is reserved to all changes 'and'modications coming within lthe scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Uni-ted States Letters Patent, is:

1. In an article of the class described, .aninatable circular tube, a continuous flexible cordlike member having longitudinally extendingzair grooves located within said inflatable tube Yfor preventing complete collapsing of .said ini'latable tube and for providing 'a stiiening structure when said inflatable tube is partially co1- lapsed, spaced rings transversely mounted within Vsaid inatable tube and .loop Yportions formed `on said .rings through which said flexible tcord- :like member passes'for supporting .the same.

2. In an article of the class described, an inflatable tube, a flexible cord-like member having longitudinally extending air grooves located within said inflatable tube for preventing complete collapsing of said inatable tube and for providing a stiiening structure when said inflatable tube is partially collapsed, and means for holding said cord-like member in a serpentine formation within said inflatable tube.

3. yIn an -article of the class described, an inflatable tube, a flexible cord-like member having longitudinally extending air grooves located within said inilatable tube for preventing complete collapsing of said inatable tube and for providing a sti'ening structure when said inflatable "tube is partially collapsed, a plurality of ringsmounted at spaced points Within said inflatable tube, and loops formed on the inner periph- `erlies foi' said rings, said cord-likemember being laced through said loops to be held in a serpen- -tineformation thereby. v
